WHAT IT DOES

What list_agents does on Tenzro Ledger MCP

AI agents call list_agents to retrieve information from Tenzro Ledger MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_agents is rated Low

This tool retrieves information about registered agents without creating, modifying, deleting, or executing any operations. It is a read-only enumeration operation with minimal blast radius if misused by an AI agent—the worst outcome would be information disclosure about network agents, which is low severity.

From the tool's definition Tool name 'list_agents' and description 'List all registered agents on the network' indicate a query/retrieval operation with no modification or execution of code.

RECOMMENDED RULE

The rule that runs list_agents safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Tenzro Ledger MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_agents, this is the rule to start with:

list_agents Allowed

list_agents is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_agents": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Tenzro Ledger MCP, apply this rule, and every list_agents call is checked against it from then on.
